When two French wingsuit divers jumped off the tip of the Burj Khalifa, the tallest building in the world, they didn't have to do it at 3 a.m. at risk of going to jail. While riding gravity for 2,717 feet, Frédéric Fugen and Vince Reffet enjoyed the sponsorship of the Emirates Aero Sports Federation, among other national skydiving organizations. Red Bull got a nice plug, too.
